Uinnin lajianalyysi ja valmennuksen ohjelmointi
Laine, Tanja 2008. Uinnin lajianalyysi ja valmennuksen ohjelmointi. Liikuntabiologian laitos, Jyväskylän yliopisto, 62 s. Uinti on neljänneksi suosituin liikuntamuoto suomalaisten lasten, nuorten ja aikuisten keskuudessa. Myös uimaseurojen harrastajamäärät ovat kasvussa. Uimaseurat ovatkin uintitoiminnan perusta ja ne järjestävät harrastusmahdollisuuksia hyvin monenlaisille ja monentasoisille ryhmille. Myös Uimaliiton koordinoima valmennusjärjestelmä on monitasoinen ja etenee portaittain lapsista aina huipputasolle asti. Suomi on kansainvälisestikin merkittävä uintimaa, jolta odotetaan myös jatkossa menestystä aina olympiatasolta asti. Kilpaurheilulajina uinti vaatii monipuolisia fyysisiä o…
Individual Endurance Training Prescription with Heart Rate Variability
Introduction: Measures of HR variability (HRV) have shown potential to be of use in training prescription. Purpose: The aim of this study was to investigate the effectiveness of using HRV in endurance training prescription. Methods: Forty recreational endurance runners were divided into the HRV-guided experimental training group (EXP) and traditional predefined training group (TRAD). After a 4-wk preparation training period, TRAD trained according to a predefined training program including two to three moderate- (MOD) and high-intensity training (HIT) sessions per week during an 8-wk intensive training period. The timing of MOD and HIT sessions in EXP was based on HRV, measured every mornin…
PGC-1 isoforms and their target genes are expressed differently in human skeletal muscle following resistance and endurance exercise
The primary aim of the present study was to investigate the acute gene expression responses of PGC-1 isoforms and PGC-1a target genes related to mitochondrial biogenesis (cytochrome C), angiogenesis (VEGF-A), and muscle hypertrophy (myostatin), after a resistance or endurance exercise bout. In addition, the study aimed to elucidate whether the expression changes of studied transcripts were linked to phosphorylation of AMPK and MAPK p38. Nineteen physically active men were divided into resistance exercise (RE, n = 11) and endurance exercise (EE, n = 8) groups. RE group performed leg press exercise (10 9 10 RM, 50 min) and EE walked on a treadmill (~80% HRmax, 50 min). Muscle biopsies were ob…
Predictors of individual adaptation to high-volume or high-intensity endurance training in recreational endurance runners
The aim of this study was to investigate factors that can predict individual adaptation to high-volume or high-intensity endurance training. After the first 8-week preparation period, 37 recreational endurance runners were matched into the high-volume training group (HVT) and high-intensity training group (HIT). During the next 8-week training period, HVT increased their running training volume and HIT increased training intensity. Endurance performance characteristics, heart rate variability (HRV), and serum hormone concentrations were measured before and after the training periods. While HIT improved peak treadmill running speed (RSpeak ) 3.1 ± 2.8% (P < 0.001), no significant changes occ…
Monitoring Training Adaptation With a Submaximal Running Test in Field Conditions
Regular monitoring of adaptation to training is important for optimizing training load and recovery, which is the main factor in successful training. Purpose: To investigate the usefulness of a novel submaximal running test (SRT) in field conditions in predicting and tracking changes of endurance performance. Methods: Thirty-five endurance-trained men and women (age 20–55 y) completed the 18-wk endurance-training program. A maximal incremental running test was performed at weeks 0, 9, and 18 for determination of maximal oxygen consumption (VO2max) and running speed (RS) at exhaustion (RSpeak) and lactate thresholds (LTs). In addition, the subjects performed weekly a 3-stage SRT including a …
Perimän ja liikuntaharjoittelun vaikutus ulomman reisilihaksen lihassolutyyppeihin ja kapillarisaatioon
Laine, Tanja 2008. Perimän ja liikuntaharjoittelun vaikutus ulomman reisilihaksen lihassolutyyppeihin ja kapillarisaatioon. Liikuntafysiologian kandidaatin tutkielma. Liikuntabiologian laitos, Jyväskylän yliopisto, 34s. Tutkimuksissa on havaittu, että perimä vaikuttaa lihassolutyyppien jakaumaan ja kapillaritiheyteen (Rico-Sanz ym. 2003). Monet tutkimukset ovat kuitenkin havainneet myös erityyppisten harjoitusten muokkaavan erityisesti II-tyypin solujen jakaumaa (mm. Liu ym. 2002) ja kasvattavan kapillaarien määrää (mm. Zoladz ym. 2005). Tämän tutkimuksen tarkoituksena onkin selvittää, määrittääkö perimä vai liikunta-aktiivisuus enemmän ihmisen lihassolutyyppijakaumaa ja kapillaaritiheyttä.…
A Submaximal Running Test With Post-Exercise Cardiac Autonomic And Neuromuscular Function In Monitoring Endurance Training Adaptation
Vesterinen, V, Nummela, A, Laine, T, Hynynen, E, Mikkola, J, and Häkkinen, K. A submaximal running test with postexercise cardiac autonomic and neuromuscular function in monitoring endurance training adaptation. J Strength Cond Res 31(1): 233-243, 2017-The aim of this study was to investigate whether a submaximal running test (SRT) with postexercise heart rate recovery (HRR), heart rate variability (HRV), and countermovement jump (CMJ) measurements could be used to monitor endurance training adaptation. Thirty-five endurance-trained men and women completed an 18-week endurance training. Maximal endurance performance and maximal oxygen uptake were measured every 8 weeks. In addition, SRTs wi…
